' 4 Claims. 1.

The present invention relates to' a metalhermetically sealed orair-tight tearing strip'container or can having one or more'interiorcollars arranged inside'of the can and hasparticular reference to amultiple part body having sections spaced apartbut secured tothe collarorrcollars in one or more'circumerential jointswhichcan be soldered fromthe exterior ofthe container and the container after opening can behermetically resealed by a replaceable air-tight reclosure'cover. Theusual tearing strip' collar container after opening can be recovered ascontradistinguishedf from resealed by the detached can endor cover. Thisbeing so it is not necessary that the collar be joined to the can bodyin a sealed joint and" Soldering of the collar to the can bodyy would'appear to make fora simple and efficient air'-v tight reclosure at suchjunctionk but soldering necessarily must be carried outon the inside"vof` the can body and this presents many manufac turing diiiiculties. n

The present invention contemplates the forming of the body member byjoining two'or more separate complete tubular can body sections throughthe intermediacy of one or more interiorAk beaded collars in such amanner as to cause the bead of the collarto function as a spacer elementfor the adjacent body elements, this'construction exposing the adjoiningedges Aof the body sections4 as well as the collar bead on the outsideso'that an eiTcient soldered joint may be easily made at this connectionby'exterior soldering.

An object of the invention is the provision ofa multiple part containerbody joineditogether by i one or more connecting interior collarsand'providing a container inwhich the body sections'are spaced apart bythe collars With'the lines'of'juncr ture exposed to the outside orcontainer exterior from which it is soldered.

Another object ofthe invention is theprovision of a reclosuretearingfstrip containerconstructed of two independent body sections andaconnecting interior collar all joined in an' exter-l iorly solderedjoint in which after opening of the container by removal of thetearingstrip, theopened container is reclosed in anair-tight jointV by sealingthe collar. l

Still another objectisthe provision'ofa tear'-` ing strip collarcontainer ofthe character de`'v scribed in which thecollar carries areclosure :z which is exposed to accessfor` resealing' purposes byinitial opening of the can.

Numerousother objects and advantages ofthe invention'willbe apparent asAit is better understood from the vfollowing description, which, taken inconnection with=the accompanying drawings,`

discloses a preferred embodiment thereof.

Referring to the drawingsz- Figure A1 isa perspective viewbf a multiple'body soldered container embodying the present invention;

Fig. 2 is' anenlarg'ed sectionalview taken sub'- stantia'lly alongsection line'- 2"-2-in Fig. 1; and

Thepre'sentinvention embodies a container formed"r offa'pluralityorvmultiple number of independent*can bodies.v drawings, these body partsmay consist of Va body section llfand'a'bodysection 12;- The bodysections are each frictionallytt'ed'on a connecting interiorv collar I3.This collar is beaded as at I4`r isexposed'onlthe exteriorof thecontainer.v This construction makes for easy soldering of the parts' asat i5 by applicationv of the solder to the outside Wall and Vthus-lendsitselfto arapid commercial I'soldering operation. Obviously ifa longercan isjdesir'edimore than two can body sections can' paused with'fthe'-necessary number of icon'- necting collars:v

screwing the'reclosure cover 35.

From the beaded portion I4, the collar I3 ex'- tends along the interiorof the body section II, this being onejof the tightly iitting parts ofthe collar. At the lower score line 2| the collar wall extends inwardlyand upwardly in a double rounded corner 25 which merges into acylindrical vertical wall 26 spaced inwardly from the body wall.

In other words this wall 26 is of a smaller diam--` eter. At the top theinterior wall 26 terminates in an inwardly extending reclosure curl 2'Iwhich provides a smooth mouth and reclosure seat for the upper scoreline extends into the upper double seam locality I9, this portion of thebody wall being designated by the numeral 3|.

A reclosure cover 35 is contained Within the can and is of suchconstruction as to be lightly carried on the interior collar I3 when thecan is sealed initially but is made usable as a reclo-V Y merges into aconical wal1r43. At the inside and at the top the conical wall 43extends by a gently curved corner '44 into a central panel 45.Preferably the plane of the central panel 45 passes through the top ofthe arched section 38 so that the cover 35 constitutes in effect a flushcover. Cooperating Vthreads 48, 45 are formed respec- The body wall IIabove v sections thereof spaced apart, an interior spacer tively in thecollar wall 26 and in the cover skirt A sealing Ygasket 5Iis disposed inthe annular groove formed on the under side of the arch wall 38. At thetime'the can is readyV to be initially sections by means of aninterposed interior collar insures that the collar can be easily andefficiently soldered within the body.

It is `thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that various changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope 0fthe invention or sacricing al1 of its material advantages, the formhereinbefore described being Y merely a preferred embodiment thereof.

The gasket 5I isconcerned with the re-Y closing. of theopened container and this light engagement is only a carrying position.When the top cover is seamed onto the can and it is fully sealed (as inFig. 2) there is no danger of the enclosed reclosure cover 35 becomingunscrewed eventhough it is only loosely applied, as the outer cover Ilprevents such displacement. f

Upon removal of the tearing strip 23, the top end closurell togetherwith the detached body wall part SI may be thrown away as no longer ofservice.
